Hello everybody.
I've just start studying theTinyOS and I have some problems about
parametrized intefaces.
The code I wrote is below (this app is something that should simulate
a traffic light, I know that I could did it in another way, but I did
it so just as exercise)
=====================================================
configuration Semaforo {
}
implementation {
components Main, SemaforoM, TimerC, LedsC;
Main.StdControl -> TimerC.StdControl;
Main.StdControl -> SemaforoM.StdControl;
SemaforoM.Timer -> TimerC.Timer[unique("Timer")];
SemaforoM.Leds -> LedsC;
}
=====================================================
module SemaforoM {
provides {
interface StdControl;
}
uses {
interface Timer;
interface Leds;
}
}
implementation {
command result_t StdControl.init() {
call Leds.init();
return SUCCESS;
}
command result_t StdControl.start() {
return call Timer.start[1](TIMER_ONE_SHOT, 1000);
}
command result_t StdControl.stop() {
return call Timer.stop[1]();
}
event result_t Timer.fired[1]() {
switch (call Leds.get()) {
case 1:
call Leds.redOff();
call Leds.yellowOn();
call Timer.start[1](TIMER_ONE_SHOT, 1000);
break;
case 4:
call Leds.greenOn();
call Timer.stop[1]();
call Timer.start[2](TIMER_ONE_SHOT, 300);
break;
default :
call Leds.redOn();
call Timer.start[1](TIMER_ONE_SHOT, 1000);
break;
}
return call Timer.start[1](TIMER_ONE_SHOT, 1000);
}
event result_t Timer.fired[2]() {
call Leds.greenOff();
call Leds.yellowOff();
call Leds.redOn();
return call Timer.start[1](TIMER_ONE_SHOT, 1000);
}
}
====================================
When I compile it I obtain the following errors:

==========================================
What's happening? Who illustrate me how modificate the code and tell
me why?
And... if I wanna declare the wiring as
-----> SemaforoM.Timer -> TimerC.Timer[uint8_t id];
How should I modify the module SemaforoM.nc??
Thank You!!
